Developers prefer working in Python because of its easy syntax and readability. Python is easy to learn as compared to other programming languages and this is the edge that a beginner gets. You can build your skills in Python and start solving real-world problems very quickly. Below are some steps that will help you become a Python developer.
Steps to Becoming a Python Developer
1. Read, Learn and Write
This is the fastest way to learn Python.
1. If you’re already a developer and just want to get the hang of the language, read the documentation and you will be able to figure things out. Install the Python IDE, and implement short pieces of code.
2. If you’re new to computer science then create a Python roadmap for yourself. To begin with, we recommend you enroll in the course on Coursera named, “Python for Everybody Specialization” by Charles Russell Severance (Dr. Chuck). This course introduces fundamental programming concepts using Python programming language including:
- Data structures
- Networked application program interfaces
At the end of this course, you will be able to design and create your own applications for data processing, retrieval, and visualization.
Along with the video lectures, you can also work your way through some textbooks if that is your preferred method of learning. Below you will find a few examples.
1. “Python Crash Course, 2nd Edition: A Hands-On, Project-Based Introduction to Programming” by Eric Matthes is available on Amazon and is among the best-selling Python books for beginners in the world. The book helps you:
- Use powerful tools and libraries in Python.
- Build 2D games that take input from the keyboard.
- Generate interactive visualization projects.
- Create web applications on the cloud.
- Resolve errors with debugging techniques.
2. There is another book, “Python Basics: A Practical Introduction to Python 3” by David Amos. It gives a step-by-step roadmap to developing fundamental skills through Python concepts and a practical approach towards building programs.
Python is a general-purpose language and over time you will get to know its enhanced features and the capabilities it provides to developers. The Python libraries and framework are very versatile. They eliminate the overhead of manually writing code for each sub-function. You can do easy coding by including some relevant libraries in your code and using their built-in functions. Other programming languages do not offer this flexibility which is why it is easier to learn as compared to Java, C++, or any other programming language.
The Python IDEs are very user-friendly. Their functions and features help you develop robust web applications. From error detection to testing, the compilers are very intelligent. All you need to do is take some Python developer training courses, watch some video tutorials, read comprehensive documentation of Python, and start writing small codes.
2. Develop Projects
Get hands-on experience in Python. Work through the projects and assignments given in your text or online course. Nothing will be better than learning by doing. Remember you are doing this for yourself. If you have basic computer science and programming knowledge, you can aim at slightly more complex projects that require more skills. These assignments and projects will clear your concepts and sharpen your skills.
As a beginner, you should choose a project idea that is not very complex but incorporates basics and some advanced concepts of Python. Through a project, you will be able to learn the Python libraries, use-cases, and their performance or complexity.
- Binary Search Algorithm
- Sorting Algorithms (Selection sort, Bubble sort, Insertion sort, Merge Sort, etc.)
- Fibonacci (very important)
- Alarm Clock
- Number Guessing
- Rock, Paper, Scissors
- Dice Rolling Simulator
At an advanced level, you can also build a web service, a price prediction model, a sentiment analysis model, or any other AI/ML model. The more you will practice, the more you will get to know the nitty-gritty details.
3. Own your Projects
Show confidence in projects you have developed on your own. For this, you can make your portfolio and a detailed document that describes all the services, libraries, and functions that you have used and implemented. Mention the applications you built with a brief overview of what they do. Look out for more projects that seem fascinating to you. Showcase your work with enhanced visuals and graphics.
4. Choose the Field/Role
When you find yourself with enough understanding and experience with Python programming languages, it is time to dive into your favorite field. Python developers get endless opportunities in Tech companies. The software houses are working on high-end projects that are exclusively built on Python. From data science jobs to machine learning engineers, there is a wide range of positions and roles for Python developers. Get to know your interests, look for job openings, and get into the field.
